Meet the Twenty.
One of them is you.
Korean saju reads your birthday as eight characters. Pick yours — your Day Master steps out of the Joseon court, and they'll read your chart with you.
Every reading for your chart. $29, once.
All 8 paid readings — one question, love, reunion, gunghap, wealth, career, 2027 and the complete 16-chapter reading. No subscription.
Ten Day Masters, each a 도령 or a 낭자.
Every birthday belongs to one of ten Day Masters. Ours come from a Joseon storybook — and the one that matches yours reads your chart with you.
New to saju? Start here.
Your sun sign is shared by 1 in 12. Your day pillar, by about 1 in 60.
Saju uses the year, month, day and two-hour window you were born — 518,400 possible combinations — and reads how five elements support, drain and shape you.
10:30 on the clock in Seoul → 09:58 true solar time
Saju runs on the sun, not the clock. We convert your birth time at your birthplace's longitude, remove historical daylight saving, and change years and months at the exact solar terms (절기).
Good to know
Who are the Twenty?
Original characters we created for the ten Day Masters of Korean saju, each as a young Joseon-era doryeong (gentleman) or nangja (lady). They are illustrations, not real people.
What if I don't know my birth time?
You still get three of your four pillars, including your Day Master. We never guess the hour.
Is this written by AI?
Your chart is calculated by our own tested engine. Reading text is written with AI from that calculation and a curated saju knowledge base, and the character art is AI-assisted — both labeled as such.
Does it predict my future?
No. Saju is a centuries-old Korean lens for self-reflection. We describe tendencies and timing themes — never health, death, money decisions or legal outcomes, and never another person's choices.
